Claims

[Scope of utility model registration request]

a solenoid valve connected to an end of the hot water supply path, a return path that communicates a portion near the hot water supply path with an inlet water path of the water heater, and a water temperature sensor that detects the water temperature of the hot water supply path or the return flow path near the solenoid valve; The system is equipped with a pump interposed in the reflux path and a control circuit that operates the pump when the water temperature detected by the water temperature sensor falls below a predetermined set value, and includes a built-in switch element and a control circuit that operates the pump when the water temperature detected by the water temperature sensor falls below a predetermined set value. A mat placed on the floor nearby is provided, and the control circuit starts the operation of the water heater and the pump when the user steps on a switch element on the mat, and controls the water temperature detected by the water temperature sensor to a predetermined level. A hot water supply piping system characterized in that the electromagnetic valve is configured to close when the temperature falls below a set value.
